Welcome to The International Hypnosis Research Institute Web site. Our intention is to support and promote the further worldwide integration of comprehensive evidence-based research and clinical hypnotherapy with mainstream mental health, medicine, and coaching. We do so by disseminating, supporting, and conducting research, providing professional level education, advocating increased level of practitioner competency, and supporting the viability and success of clinical practitioners. Although currently over 80% of our membership is comprised of mental health practitioners, we fully recognize the role, support, involvement, and needs of those in the medical and coaching fields. This site is not intended as a source of medical or psychological advice. -- Tim Brunson, PhD

Hypnotizable (N = 9) and simulating subjects (N = 8) were age regressed to the previous week's hypnosis session and received a suggestion to hear a phone ring during the earlier session (no phone actually rang). Pseudomemory rates in response to open-ended questions were low in this study (0% hypnotizable and simulating subjects) and in previous research (Lynn, Weekes, & Milano, 1989; 12.5% hypnotizable; 10% simulating subjects) in which the phone-ring suggestion was not embedded in the context of age regression. In response to a forced-choice question, 22.22% of the hypnotizable and 25% of the simulating subjects indicated that the suggested phone ring was an actual event, a pseudomemory rate somewhat higher than our previous study in which none of the subjects reported pseudomemories in response to a forced-choice question. When the occurrence of the target stimulus of a pseudomemory suggestion is publicly verifiable, the pseudomemory rate is low.
